Questions?

FAQs, answered

What is secure email?

Secure email combines encryption and recipient authentication to protect messages from interception and unauthorised access. It helps prevent data breaches, even if an email is sent to the wrong person.

Why isn't regular email secure?

Standard email travels through multiple servers and was never built for privacy. Without encryption, contents can be intercepted or altered in transit. Inbox takeovers and misdirected emails pose additional risks.

How is Mailock different?

Mailock adds identity checks to email, verifying recipients before access. It includes military-grade encryption, security alerts, and features for both individual and high-volume use, making it ideal for sensitive communications.
